IMPROVEMENT lN DUST-FANS Specification forming part of Letters PatentNo. 190,499, dated May 8, 1877 application filed September 21, 1876.

To all whom it may concern:

Be it known that I, ISAAC S. LAU'BAGK, of Chicago, in the county of Cookand State of Illinois, have invented new and useful Improvements inDust-Pans; and I do hereby declare the following to be a full, clear,and

exact description thereof, which will enable others skilled in the artto which my invention appertains to make and use the same, referencebeing had to the accompanying drawing, forming part of thisspecification, in which the figure represents a general plan or top viewof a dust-pan embodying my said invention.

The object of my invention is to simplify the construction of dust-pans,so as to lessen the cost of manufacture, and make them stronger and moredurable.

To that end my invention consists in the novel construction of the bodyof the pan, as is hereinafter described.

In the drawing, A represents the body of the pan, which is made of anysuitable sheet metal commonly used in' the manufacture of dust-pans. Bis the handle, which is also made of sheet metal, and is riveted orotherwise secured to the body A, in the usual manner. The blank fromwhich the body is formed is first cut in the shape desired, and theouter edge thereof is then strengthened or stiffened by wiring, in theusual manner; or the edge may be turned over or hemmed, as may bepreferred. The blank is then stampedin shape, to form the body of thepan, by means of suitable dies of the required form, which will bend theblank so as to form an upward-projecting flange, a, extending across theback and on each side of the body, as shown in the drawing.

The flange at the back of the body describes an arc of a circle, and isconcaved toward the base or bottom of the pan, and is bent at its upperedge, so as to form a series of corrugations,d, as shown, the object ofsaid corrugations being to strengthen the body of the pan, and take upand utilize the surplus metal.

I am aware that dust-pans have been made having the flange at the back,arranged at a right angle to the flanges at the sides, and wired orhemmed at the upper edge of the flange, after the blank has been formedin the shape desired, which requires more labor to manufacture them, andthey cannot be made with the ease and accuracy as when made by firstwiring or hemming the blank, as above described. By my said method I amenabled to furnish a cheaper and better finished article, and with amuch less loss of imperfect blanks in the process of manufacture.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

As a new article of manufacture, a dustpan having the body thereof madecircular at the back, and from a single piece of sheet metal hemmed orwired at its upper edge, said wired or hemmed edge portion beingcorrugated with the rest of the back, substantially as and for thepurpose specified.
